The Wizard of Oz is one of my favorite spiritual tales, and Glinda is a spiritual goddess. I love when she says to Dorothy, "You've always had the power." That is the message for all of us. You're born with it, you always have it. It doesn't matter how many yellow brick roads you go down, it's always right there in your heart.

Katy Perry, Rosie Huntington-Whiteley, Dakota Johnson, and Jessica Chastain also participated in the shoot. See the full Icons portfolio over at HarpersBazaar.com. The images are all pretty amazing.
